Abstract
The utility model relates to a kind of flag-shaped foundation pit enclosure structure in Foundation Pit Support Engineering field, this foundation pit enclosure structure comprises gear fortifield village's protection structure (1), diagonal brace (2) and reinforcement cushion (3) three part, and the syndeton possessing hinge function is set between this three part, form stable gear soil water-stopping structure, this flag-shaped foundation pit enclosure structure is applicable to all kinds of soil layer and multiple degree of depth foundation ditch, considerably reduce bracing of foundation pit cost, speed of application is fast, safe and reliable.
Description
Technical field
The present invention relates to the bracing of foundation pit field in geotechnical engineering field.
Background technology
Steel pipe pile diaphragm wall achieves the full recovery of the bracing of foundation pit soil-baffling structure under all kinds of geological conditions such as weak soil or pan soil of all kinds of degree of depth as the full foundation pit enclosure structure reclaimed, but for the foundation ditch that the degree of depth is darker, in bracing of foundation pit, still need to arrange anchor pole or support system as horizontal bearing structure, inner support system is for deep big foundation pit, cost is very expensive, and the construction period is long, waste of material is serious, anchor structure is general longer, surmount underground red line, and be not suitable for Soft Deep Foundation Pit, the recovery operation face of anchor pole is narrow and small, recovery difficult is large, the rate of recovery is low, support according to taper pile, then taper pile consumption is more, how to play foundation soil potentiality better, design technique simple, safe and reliable foundation pit enclosure structure be still engineering construction in the urgent need to.
Summary of the invention
The object of this invention is to provide a kind of flag-shaped foundation pit enclosure structure, this foundation pit enclosure structure speed of application is fast, and cost is low, and degree of safety is high, easy construction.
This flag-shaped foundation pit enclosure structure comprises gear fortifield village protection structure, diagonal brace, reinforcement cushion three part, during gear fortifield village protection structure is wherein stop excavation of foundation pit, the outer water and soil in hole enters the structure of foundation ditch, diagonal brace is the structure with certain rigidity and intensity tilting to construct inside foundation ditch, reinforcement cushion is the steel concrete tabular structure being positioned at subsoil top, hole, foundation ditch inside, and possesses the syndeton of hinge function at gear fortifield village's protection structure and diagonal brace, diagonal brace and reinforcement cushion, setting between reinforcement cushion and gear fortifield village protection structure.
In above-mentioned flag-shaped foundation pit enclosure structure, above-mentioned gear fortifield village protection structure can be the one of steel pipe pile or steel pipe pile diaphragm wall, can be the syndeton formed with the concrete that steel pipe pile or steel pipe pile diaphragm wall weld after-pouring reinforcement cushion by the reinforcing bar of reinforcement cushion keeping off fortifield village's protection structure with the syndeton between reinforcement cushion.
In above-mentioned flag-shaped foundation pit enclosure structure, can arrange at above-mentioned gear fortifield village protection structure top and enclose purlin.
Flag-shaped foundation pit enclosure structure of the present invention, is applicable to all kinds of soil layer such as weak soil, pan soil, and is applicable to comparatively deep foundation ditch, can significantly reduce shoveling difficulty, improves speed of application, reduces engineering cost.
Accompanying drawing explanation
Fig. 1 is one embodiment of the present of invention flag-shaped foundation pit enclosure structure generalized sections used.
Detailed description of the invention
As an embodiment as shown in Figure 1 of the present invention, main purpose is structure structure and the operating principle of introducing a kind of flag-shaped foundation pit enclosure structure of the present invention.This flag-shaped foundation pit enclosure structure comprises gear fortifield village's protection structure (1), diagonal brace (2), reinforcement cushion (4) three part, during gear fortifield village protection structure (1) is wherein stop excavation of foundation pit, the outer water and soil in hole enters the structure of foundation ditch, diagonal brace (2) is the structure with certain rigidity and intensity tilting to construct inside foundation ditch, reinforcement cushion (4) is for being positioned at the steel concrete tabular structure on subsoil top, hole, foundation ditch inside, and at gear fortifield village's protection structure (1) and diagonal brace (2), diagonal brace (2) and reinforcement cushion (4), between reinforcement cushion (4) and gear fortifield village's protection structure (1), the syndeton possessing hinge function is set.In above-mentioned flag-shaped foundation pit enclosure structure, above-mentioned gear fortifield village protection structure (1) can be the one of steel pipe pile or steel pipe pile diaphragm wall, and being positioned at gear fortifield village's protection structure (1) and the syndeton between reinforcement cushion (4) can be the connection of to be welded with steel pipe pile or steel pipe pile diaphragm wall by the reinforcing bar of reinforcement cushion (4) and being formed after building the concrete of reinforcement cushion.In above-mentioned flag-shaped foundation pit enclosure structure, can arrange at above-mentioned gear fortifield village protection structure (1) top and enclose purlin (3) to improve the globality of gear fortifield village's protection structure (1).Flag-shaped foundation pit enclosure structure of the present invention, because of gear fortifield village's protection structure (1), all being hinged is there is between diagonal brace (2) and reinforcement cushion (4), the stable plane triangle that formation can effectively carry, utilize hole subsoil bearing capacity, by reinforcement cushion (4) and gear fortifield village's protection structure (1), soil pressure outside the acting in conjunction balance foundation ditch of diagonal brace (2), because there is being hinged between reinforcement cushion (4) and gear fortifield village's protection structure (1), therefore reinforcement cushion (4) can be utilized to balance the soil body gravitational difference of foundation ditch inner and outer, effectively can prevent bottom heave, and the insertion depth keeping off fortifield village's protection structure (1) can be reduced.In the present embodiment, if gear fortifield village's protection structure (1) is bored pile, then the bar connecting that will keep off fortifield village's protection structure (1) and reinforcement cushion (4) by bar planting on bored pile is formed and is hinged.In the present embodiment, by arranging built-in fitting on reinforcement cushion (4), built-in fitting and diagonal brace (2) are connected to form being hinged between reinforcement cushion (4) and diagonal brace (2).Gear fortifield village's protection structure (1) and the connection between diagonal brace (2) can be passed through directly to weld, arrange various ways such as enclosing purlin (3) welds again, bolt connection is formed and is hinged.In the present embodiment, can jump along the segmentation of foundation ditch length of side direction digs to the end, hole, and branch completes flag-shaped foundation pit enclosure structure and installs, and namely first completes the bracing of foundation pit of first excavation section, complete the installation of excavation and the flag-shaped foundation pit enclosure structure staying native section again, thus reach bracing of foundation pit object.
This patent includes but not limited to other construction methods of the alternative use of professional person in this area.
